Quality Test Cases

This relates directly to the saying “quality over quantity.” A good manual testing case has the highest probability of finding defects. A manual tester has to research what COULD go wrong in each functionality by reviewing the requirement documents, in order to produce and review effective test cases.

Manual Testing: Learn To Analyze Your Own Results

Simply discovering whether a test result is “pass” or “fail” is just the bare bones of your job when it comes to manual testing. If you want to stand out from the average and lazy testers or even just earn some noticeable respect, troubleshoot your bugs. Find out what the root cause is of a “fail” and provide possible solutions in your manual testing report.

Regression Testing

Applications are updated all the time. The needs of users are always changing and technology is advancing. Sometimes changes to an application affect other unchanged functionalities. This is why regression testing is highly recommended. A QA tester should have some set regression tests to make sure that all major functions are working properly in an application after each change.

Run Test Cases By the Developer

It is good practice to give the test cases to the developer so they can verify if they cover all of the main functionalities or not. Communication is the most important skill contributing to effective testing. Talking with your developer about the manual testing cases before they are run also ensures that re-working them will be minimal.

Keep Developers Away From The Test Environment

Yes, running a manual testing case by the developer is fine but when they end up doing some of the testing themselves, things can get hairy. Keeping them away from the environment is imperative to detect any configuration changes missing in release or deployment documents. Sometimes developers make these changes and forget to mention them in the deployment steps. If the developer doesn’t have access to the manual testing environment they can’t accidentally make these changes within the environment leaving these types of inconsistencies to be found at the right spot.

Manual Testing: Go Beyond Requirements

Test an application for what it is NOT supposed to do. Users won’t know every nook and cranny of an application or know all of its intended functions at a glance so they may accidentally use it the wrong way.

Increase Your Knowledge Of The Product By Speaking With The Developer

You want to know as much about the product as possible. Speaking with the developer is obviously the best way to gain an understanding of an application since they have built or are the one building it. Also resolving disputes face-to-face helps teams work through things the most efficiently. Always clarify the outcome of a dispute over written communication for future reference and verification.


As a QA tester you need to make sure your tasks are aligned in an order of high to low priority. This will make sure you get the most important tasks done well. You don’t want to run out of time while having high priority tasks hanging over your head.

Divide And Conquer

Dividing an application into smaller unit modules enables a QA tester to delve deeper into each part of the application and find the most difficult bugs while allowing them to understand the application more comprehensively.

Be Aware Of Performance Testing

This is when an application includes certain features that should be working properly like a response time in a banking application or timeout features on applications selling limited supplies like concert tickets.

Be Positive

Start the manual testing of an application KNOWING you are going to find bugs and errors. Don’t just test it to see if it works. You will find a lot more subtle bugs if you go in with that intention and mindset.

Write A Clear And Concise Bug report

As I mentioned earlier, communication is the most important thing when testing applications. Bug reports are that form of communication so it is absolutely essential that they are written well if you want to be your customer’s dream UAT testing agent.
